Coccidiosis and its Phytogenic Control: A Review

Abstract

Coccidiosis remains a major parasitic disease of poultry, caused by protozoa of the genus Eimeria, leading to substantial economic losses through reduced performance, morbidity and mortality. Traditional control measures have relied primarily on anticoccidial drugs, supplemented by limited vaccine use. However, the prolonged and extensive use of chemotherapeutics has resulted in the emergence of drug-resistant Eimeria strains and concerns over drug residues in poultry products. These challenges have shifted research focus toward alternative, sustainable control strategies, particularly phytogenic compounds known for their safety, cost-effectiveness and broad biological activities. This review summarizes current research on plant-derived substances with anticoccidial potential, highlighting their bioactive components, effective dosages and mechanisms of action. The information presented may support the development of improved and eco-friendly strategies for coccidiosis control in the poultry industry.
